Research progress on pharmacokinetics and pharmacological activities of artesunate / 中国中药杂志

ABSTRACT

Artesunate (AS), a famous derivative of the artemisinin, is the basic treatment globally for mild to severe malaria infection due to the prominent advantages such as high efficiency, fast effect, low toxicity and not easy to produce resistance. More and more research reports have shown that AS and its active metabolites dihydroartemisinin (DHA) had various bioactivities in addition to antimalarial activity, attracting researchers to further study its new pharmacological effects in order to explore new use of the old drug. A comprehensive understanding of the pharmacokinetic characteristics of AS will be conducive to the further development of new pharmacological actions and clinical application of AS. Therefore, this paper would review the absorption, distribution, metabolism and excretion of AS , as well as the pharmacokinetics characteristics of AS and DHA after clinical administration of AS by intravenous (IV), intramuscular (IM), oral or rectal routes. The process and pharmacokinetic parameters of AS and DHA were compared between healthy volunteers, malaria patients, and special populations (children, women). Meanwhile, the research progress on pharmacological effects of AS and active metabolite DHA such as anti-tumor, anti-inflammatory, anti septic, antiangiogenic, anti-fibrosis and immunoregulation activities would be also reviewed, hoping to provide a theoretical basis for the further development and utilization of AS and its metabolites.
